note 56319 added to function.imagejpeg

whenever i want to save the new picture i generated in the site, it doesn't have a filename or file size. i mean, i used this: header("Content-Disposition: attachment; filename=image_name.jpg"); and still, whenever i click right click and do properties i get: "file size unknown" and when i try to save the file, the file type and name are unknown as well. for example, instead of having the option to save at as jpg, i get only Bitmap (bmp). what can be done to fix that? ---- Manual Page -- http://www.php.net/manual/en/function.imagejpeg.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+56319 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+56319&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+56319&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+56319&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+56319&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+56319&report=yes&reason=non-english Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+56319&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+56319&report=yes Search -- http://master.php.net/manage/user-notes.php
